Hand History

villain is unknown
on the flop, I hit top pair and flush draw
it is complicated situation for me.
if I have only top pair weak kicker, lets say A9dd, I would definitely check back
since my purpose is go to show down cheaply.
if I have only flush draw, lets say KJhh, I would definitely bet to make him to fold
or make the pot bigger and get value if I make flush ott or otr.

what about this situation? I think either option is fine but check back is better
because I do not have to have fold equity at this time and my check can hide my flush draw.
wanna know your opinions.
